Can't print to HP Officejet 6210 from Internet Explorer

Hey All,

I am having trouble printing from Internet Explorer. when I try to print, I
get the message "This action is restricted. For more information, please
contact your system administrator."

I am logged in as administrator. What can I do to fix this? I can print fine
elsewhere, just not from IE. Here's my system info:
Vista Ultimate RC2 build 5744
Intel Pentium D 820
HP Officejet 6210 All-in-One with Microsoft drivers

Thanks in advance for any replies.
